Overview
The AH series explosion-proof junction box is die-cast from aluminium alloy and finished with a high-pressure electrostatic powder coating, with stainless steel exposed fasteners throughout. Cable entries are G1/2–G2 or M20–M63×1.5, rated AC 220/380 V at 20 A. The range covers 1-way, 2-way, 3-way, 4-way, angle and pendant lamp box configurations, so lighting and power circuits in classified areas can be terminated and looped from a single enclosure family.
